Question 5
pantera1 [17]

Answer:

The solubility of a gas in a liquid occurs faster if the liquid is cooled. Hence the correct answer is option B.

Explanation:

The solubility of a gas in a liquid occurs faster than a solid. Solid solute takes much time to be dissolved in a solvent. This is because of the bonding. The bond of the solid is is much stronger when compared to the gaseous state. This is one of the reasons of gaseous dissolving faster than solid.

A gaseous state is defined as a material whose atoms are not closely attached with one another and is free to move in any direction. And when we have to mix gas in a liquid in a faster rate the liquid temperature should be lowered.
